Printer Stepper Motor Drivers 8W, 12V Fluorescent Lamp DN DN Fluorescent tubes are notoriously difficult loads to drive. Before striking, the tube effectively appears open circuit, needing V or greater to provoke conduction. After striking they adopt a low voltage characteristic where the required current can be sustained at low. www.doorway.ru Stafford St. Worcester, MA Tel. 1 () Fax www.doorway.rund: Eiko. Description. This Fluorescent Emergency driver battery backup kit l is a energy-saving emergency solution.
Printer Stepper Motor Drivers 8W, 12V Fluorescent Lamp DN DN Fluorescent tubes are notoriously difficult loads to drive. Before striking, the tube effectively appears open circuit, needing V or greater to provoke conduction. After striking they adopt a low voltage characteristic where the required current can be sustained at low. A capacitor is put in series with the secondary winding. At first, the high idling frequency and voltage pass to the lamp rather directly, as it is electrically inactive. After start, the voltage collapses from several hundred volts to the operating voltage, which is ca 70V for an 8W rod. Ionization wires can be applied in addition. An 8 W standard fluorescent tube can be efficiently driven using the circuit. The two transistors (2SC) with associated components forms a oscillator around 1KHz. The oscillator is wired so that saturation condition of the transistors are prohibited.
Without changing the T8 fixture, a T5 fluorescent lamp can be fitted into the fixture with a T8-T5 8: T8 Conventional Lighting System Circuit Diagram. 8 Watt Linear Fluorescent Tube Replacement Light Transformer Robertson P 9W CFL F4T5 F8T5 Simple Reactance Ballast V. Robertson. SKU: RB-OP. This voltage is high enough to directly start a low power fluorescent tube without preheating the electrodes. It works fine with 4 W tubes and with many 8 W.
